CULVERT.

Specification of Letters Patent.

Application filed March 9, 1911.

To all whom it may cancer-n:

Be it known that 1, JOHN Gmson, a citizen of the United States, residing at Fromherg, in the county of Carbon and State of hloutana, have invented certain new and useful Improvements in Culverts, of which the. following a specification.

My invention'relatcs to culverts and has for its object the improvement of culverts by forming them of blocks of reinforced concrete, each block forming a complete transverse section of a. culvert channel, said blocks being of a size capable of easy transportation and in assembling bound together by" rods arranged longitudinally of the culvert. structure and cross rods secured to the longitudinal rods between the several blocks and at the ends of-the' structure.

My invention will be described in detail hereinafter and illustrated in the accompanying drawings in which Figure 1 is an end view of a culvert consisting of a single channel, Fig. 2, a similar view of a culvert consisting-of two parallel channels, Fig. 3, a longitudinal sectional view through one of the channels in Fig. 2, and Fig. 4, a side View of the culvert shown in Figs. 2 and 3.

In the drawings similar reference characters will'l be' used to indicate'corresponding parts in the several views. My improved culverts as shown 111 Figs.

1 and 2 are composed of a plurality of blocks 1 of reinforced concretematerial, the blocks used in the culvert'illustrated-in Fig. 1 being designated 1. Blocks "1, as shown,

are in form complete cross-sections of the culvert A, having a hole 12 therein that forms the channel whenthe blocks are as sembled.

The 'sides of blocks 1 are 'formedwith notches or recesses 3 to receive longitudinal tie rods l'that serve to bind the blocks 1 togetherfend tolend, and cross rods. 5 'connecting rods 4, said cross-rods 5 in Fig. 1 being 'shown only. at the end or the'culvert but as shown in Fig. 3 the rods 15 may be secured between the several blocks as well as at the ends of the culvert.

In the culvert shown in-Fgigs. 2, 3 and 4 two parallel channelsare provided for and Patented Oct. 3, 1911. Serial No. 813,259.

it will be apparent that the multiplication of channels may be continued indefinitely, limited only by the requirements of the stream to be drained. The blocks 1 used in making culverts with a plurality of parallel channels have the notches shown at 3 to receive the tie rods 4, seated between the blocks, arranged side and side, formed semicircular in cross section so that the edges of the two sets of blocks on the two sides of the intermediate rods engage one another.

6 indicates plates mounted on'the ends of rods 4 between the blocks to more securely bind them.

As hereinbefore stated the cross rods 5 onthe culvert shown in Figs. 2, 3 and 4 are mounted between the individual blocks constituting the culvert or obviously between groups. of the blocks. T he spaces between the blocks where the cross-rods are mounted may, it found necessary, be filled with concrete or other plastic material shown at 7.

8 indicates a post positioned opposite the 1 meeting edges of the blocks 1 a short distance up stream from the culvert to form a. breakwater to -intercept floating trash and direct it into the channels flowing through the culvert openings and prevent it from lodging, against the culvert between the openings.

Having thus described my invention what I claim is 1. A culvert comprising a plurality of blocks arranged side to side, each block comprising a cross-section of a culvert channel and having recesses in their sides, and rods mounted in said recesses longitudinally of the culvert and holding the blocks in an assembled position.

2. A culvert comprising a plurality of blocks arranged side to side, each block comprising a cross-section of a culvert channel, rods secured to'the blocks longitudinally of the culvert and holding them in an assembled position, and cross rods secured to the longitudinal rods. r

A culvert comprising a plurality of blocks arranged side to side and edge to edge, each of said blocks comprising a cross.-

scction of the culvertchannel, rodssecured to the ends of the culvert and betweenthe.

blocks longitudinally of the culvert chana breakwater for the partitions between the 1s nels, and cross rods connecting the longituchannels.

dinal rods at the ends of the channels and! In testimony whereof I hereto aflix my between blocks intermediate of the ends of signature in the presence, of two Witnesses;

o the channel. v JOHN GIBSON.

l. In combination with a culvert having a plurality of channels, a post secured in a Witnesses: line between the pair of channels in advance W. W. PATIERSON, of the up-stream end of the culvert to form f GEO. W. PIERSON.
